Python using calculateSlope

Any reason you're doing it this way rather than using some of the inbuilt transformers?

The next step is to itterate over the cells to set a new height, starting from the lowest or highest cell value working up/down. This I can't do effectively with the current tools.

But if I can't get the same results doing this with python and with the slope transformer I will not start the rest of the steps.

I'm struggling to understand exactly what you're trying to achieve. For more complex Raster manipulation I have had great success coercer then to pointclouds and using some of the pointcloud transformers. These may be helpful in what you're wanting to achieve?

I think the question is, what is the correct syntax to set the setting

kFME_CalculateSlope_interpolateNodata

to

No

because

class FeatureProcessor(object):
    def input(self,feature):
            raster = feature.getGeometry()
            rst = fmeobjects.FMERasterTools()
            settings = {'kFME_CalculateSlope_interpolateNodata' : 'No'}
            raster_new = rst.calculateSlope(1,raster,settings)
            feature.setGeometry(raster_new)

seems to be not correct.

kFME_CalculateSlope_interpolateNodata

No

class FeatureProcessor(object):
    def input(self,feature):
            raster = feature.getGeometry()
            rst = fmeobjects.FMERasterTools()
            settings = {'kFME_CalculateSlope_interpolateNodata' : 'No'}
            raster_new = rst.calculateSlope(1,raster,settings)
            feature.setGeometry(raster_new)

I have this workbench and expect the same results from the rasterSlopeCalculator as the PythonCaller. But it is not working so I think I don't understand the Python documentation.

The Python_polate_no inspector should have the same result as the Slope_polate_no AND

The Python_polate_yes inspector should have the same result as the Slope_polate_yes

So i'm doing something wrong on line 5 or 6, but I don't know what.
